SEOUL, South Korea (AP) -- Asian stock markets were mostly lower Tuesday as investors continued their flight from risky assets on the prospect of slower Chinese growth and the winding down of the U.S. Federal Reserve's monetary stimulus.
Markets in China extended declines from the previous day as investors worried that measures to curb underground lending would hurt growth in the world's second-largest economy.
The Shanghai Composite Index plunged 3.8 percent to 1,888.69 and Hong Kong's Hang Seng dropped 1.4 percent to 19,533.05.
Japan's Nikkei 225 shed 1.6 percent to 12,848.96. South Korea's Kospi fell 1 percent to 1,780.81 and Australia's S&P/ASX 200 was down 0.5 percent to 4,645. Stocks in Taiwan and the Philippines also declined.
Shanghai's stock index endured its biggest loss in four years Monday after the country's central bank allowed commercial lending rates to spike higher. Analysts say the move was part of an effort to curb off-balance-sheet lending in China that could threaten the country's financial stability.
But the higher lending rates could also hurt economic growth. The impact for stock markets would be all the greater if the U.S. Federal Reserve tightens its own ultra-loose monetary policy over the coming months, as it has signaled it would do so long as the U.S. economy improves according to its forecasts.
On Monday, Wall Street closed lower. The Dow Jones industrial finished down 139.84 points, or 0.9 percent, at 14,659.56. The S&P 500 index fell 19.34 points, or 1.2 percent, to 1,573.09.
Analysts at Moody's Investors Service said they saw the Chinese central bank's action to allow lending rates to rise as "a conscious decision" to curb credit growth.
Moody's said a prolonged credit crunch could threaten Chinese companies, "especially those in the private sector with weak credit quality, because it heightens the risk that banks will scale back lending to those companies." The credit ratings agency said that China's central government finances remain strong, but that rapid credit growth and liabilities at the local level pose a threat to growth.
The concerns over China's credit market were magnified by existing worries that access to money will tighten in the world's largest economy, the U.S.
Investors are concerned what will happen as the U.S. Federal Reserve slows down its monetary stimulus program, which has been pumping $85 billion into the financial system every month and helped many stock indexes reach multiyear or record highs. Markets tumbled last week when Fed Chairman Ben Bernanke said the program would likely slow down this year and end in 2014.
